Waterproofing Your Chimney

With recent summer rainstorms bringing unexpected downpours, homeowners need to pay extra attention to their chimneys. A chimney can be a hidden source of leaks and damage if not properly maintained. Waterproofing your chimney is essential to protect your home from moisture damage, ensuring it remains safe and sound throughout the year. Here’s a step-by-step guide to help you waterproof your chimney effectively.

Why Waterproof Your Chimney?

Chimneys are exposed to the elements year-round, making them susceptible to water damage. Bricks and mortar can absorb water, leading to deterioration over time. This process can cause cracks, spalling (flaking of the brick surface), and even structural damage. Waterproofing your chimney not only prevents these issues but also extends its lifespan, saving you money on potential repairs.

Assess the Current Condition

Before you begin waterproofing, inspect your chimney for any existing damage. Look for cracks, loose mortar, or spalling bricks. If you find significant damage, it’s best to have a professional mason repair these issues before proceeding with waterproofing. Minor cracks and gaps can be filled with a high-quality chimney sealant.

Clean the Chimney

A clean surface is crucial for effective waterproofing. Remove any dirt, moss, or debris from the chimney using a wire brush and a garden hose. For stubborn stains, a mild detergent solution can be used. Ensure the chimney is completely dry before applying any waterproofing products.

Choose the Right Waterproofing Product

There are various waterproofing products available, but not all are suitable for chimneys. Opt for a breathable, water-repellent solution designed specifically for masonry. These products allow water vapor to escape from the brick while preventing liquid water from penetrating the surface.

Apply the Waterproofing Solution

1. Preparation: Wear protective gloves and eyewear. Cover the surrounding area to protect it from overspray.

2. Application: Using a pump sprayer or a paintbrush, apply the waterproofing solution evenly across the entire chimney surface. Start from the bottom and work your way up to ensure complete coverage. Be generous with the application, but avoid over-saturating any area.

3. Second Coat: After the first coat has dried (usually within a few hours, depending on the product), apply a second coat for added protection.

4. Drying Time: Allow the chimney to dry thoroughly. Check the manufacturer’s instructions for specific drying times, but typically, it takes about 24-48 hours for the solution to cure completely.

Regular Maintenance

Waterproofing is not a one-time fix. Inspect your chimney annually, especially after heavy rainstorms, to ensure the waterproofing is intact. Reapply the waterproofing solution every 5-7 years, or as recommended by the product manufacturer.

Waterproofing your chimney is a straightforward task that can save you from costly repairs and headaches down the line. However, this project should only be done if you’re completely comfortable on a roof and using a ladder. If this kind of home maintenance task isn't something you do regularly, it’s a good idea to call a professional. No home improvement job is worth a trip to the emergency room.

Mold in the Home: A Common Problem in Spring 4-4-24

Mold is an issue that most homeowners have to deal with at one time or another. It’s the damaging by-product of excess moisture that can wreak havoc on your home, and more importantly, your health. With spring in full swing, now is a good time to inspect your house for mold and get rid of it before it does any kind of serious damage. 

You might be familiar with mold or mildew from your shower or bathtub. Since the shower is often wet and the tiles are waterproof, water can sometimes seep into the grout. If the grout is old and can’t handle its repelling duties properly, it becomes a breeding ground for mildew which can generally be cleaned with a good scrub. But what happens when mold starts to grow in the places you can’t clean as easily – places like your ceiling, inside your walls, or in the attic? You’re probably saying, “Not in my house”. Well, guess again.

At least half the homes I visit for remodeling projects have a major mold problem and the owners don’t even know it. How? Because mold generally grows in places that you can’t see – like inside the walls and in the attic. What most people don’t realize is that mold reproduces by releasing spores that you’re breathing in day after day.

How common is this? If you’ve ever had a leak, you’ve most likely had a mold problem. So what can you do about it? You can prevent mold by ensuring your home stays dry. Here are my top tips:

1. Keep your gutters and downspouts clean and clear so water can drain away from the foundation of your house. 

2. Make sure the ground around your house doesn’t slope inward towards the foundation where water can idle.

3. Don’t let a leaky roof go unfixed.  Get it patched up immediately and ask your contractor to inspect for any mold growth.

4. Inside the house, beware of any discoloration on the ceiling.

5. Ensure high moisture areas like bathrooms are well-ventilated with good ceiling fans that don’t vent into the attic.

6. If a leak happens in a carpeted area, don’t just leave it to dry. A damp area can attract mold in less than 48 hours.

7. Ensure large appliances such as refrigerators and washing machines have a catchment tray in case of a malfunction.  

8. If you think your house or basement is susceptible to high moisture, consider purchasing a dehumidifier to regulate the humidity and remove any excess moisture from the air.

If you’ve had a mold problem that you’ve tried to control by scraping, cleaning, and repainting the area, don’t make the same mistake twice. If the mold keeps coming back, that means the issue runs deeper than the eye can see. It’s time to call in the pros.

Upgrade Your Gutters For Less Maintenance Year Round

While most people think about gutter cleaning in the autumn, the falling of spring blossoms can cause serious clogging that creates overflows and inadequate rainwater drainage. 

Gutters have come a long way in the past few years. Back when many of the homes in this area were built, open gutters were used to collect rain off the roof and deposit it onto the ground through a system of downspouts. Open gutters, however, allow not only water but leaves, whirlybirds, blossoms, and sticks to also fall into the gutter, blocking them and eventually causing overflow without regular removal.

Gutter cleaning keeps me busy, mainly because it’s a dirty job that can also be dangerous if you’re not used to working on a ladder. Luckily, over the past few years, gutter manufacturers have smartened up, creating shields to install over your current gutters, as well as closed gutter systems that can replace your current setup.

Gutter guards come in a variety of materials and sizes, but they are all designed to maximize water flow while keeping tree debris out of the channel. The least expensive option is steel mesh screens which slide in and sit above the gutter lip itself. The arch design helps to ensure that debris can’t get stuck in the back of the gutter and they generally come with a five-year warranty against rusting or corrosion.

A step up from mesh screens is a heavy-duty aluminum option that can be fitted from the front and back, avoiding the need to remove roof shingles for installation. These products come with a ripple design to prevent leaves from drying on the surface and they are generally backed by a 20-year warranty so you don’t have to worry about replacing them often. I like these because the design strengthens the gutter which comes in very handy during major snowstorms when many homes in the area suffer from heavy and dangerous ice dams.

Finally, there is Leaf Relief, a heavy aluminum gutter shield that can drain nearly 30 inches of rainfall in one hour, which is 15 inches more than the highest rainfall ever recorded (for inquiring minds, that’s 12 inches in one hour in Holt, Missouri). For homeowners who want no maintenance, this is the gutter product for you. The 25-year no-clog, no-overflow warranty gives it the same lifespan as a new roof and the inset design makes it invisible from the road. Best of all, dry debris blows away with only a six-mile-per-hour breeze.

No matter what type of gutter guard you choose, you want to make sure that it’s the best product for your home. While any gutter guard will reduce debris getting into your gutter, the right guard will depend on the trees in the area, how much rainfall you get, the position of your house, and the size and age of your current gutters. Once those factors are taken into consideration and the appropriate product is chosen, you can say goodbye to messy cleaning and enjoy less maintenance at your home.
